Handle AJAX error responses that come back as HTML

If an AJAX request ends up hitting some sort of error that hasn't been handled properly in the code yet, it often gets a full HTML page back as a response, instead of just a text error message. Previously, this would end up with Intercooler putting the full text of the HTML into the error element, which is really ugly and confusing. Now, it will just put an "Unknown error" message, and the actual error should still end up getting reported to me through Sentry to be able to investigate.
